Important to carry a spare auxiliary drive belt (fan belt). Can ruin a trip if one breaks, first problem is to know the part number, and second problem is to locate one. Suggest you write down the part number (take it off of the belt) and keep a note in the Morgan, and order a spare.
Next task is to investigate how the tensioner is released. On last years trip in Belgium one of the sigma engined Morgans destroyed a belt, nobody knew the part number, it was in the evening at a weekend, Morgan agents shut. They found a fragment of the belt in the road, got the part number, but unable to get that size, tried to fit a similar size but had already damaged the tensioner by forcing it. Morgan had to get trailered home.
Even if you call out a breakdown service, you will have the belt for them to install
